Phun

http://www.phunland.com/

It may look like a toy, but Phun (and Algodoo) are based on highly competitive technologies for interactive multiphysics simulation, ranging from novel physical models and variational integrators to high performance numerical methods.

Phun is an amazing little simulator that allows for endless creativity.  You can make blocks, wheels, walls, axles, motors, springs, etc and you can put them in motion and even pause, rewind, and put things into slow-motion. 








Algodoo:  Phun Grows Up!

Phun has grown up and become a full commercial product, complete with more tools like velocity vectors, color traces, light prisms, etc.  Algodoo is designed to encourage young people’s own creativity, ability and motivation to construct knowledge. The synergy of science and art makes Algodoo as educational as it is entertaining.

Build your own worlds using rigid bodies, fluids, chains, gears, springs, hinges, motors, lasers and optics. Interact with a large community and explore more than 30.000 amazing user created scenes.

If you decide to break the Freeloader tradition, you can buy it for only 29 Euros.
